Abstract

1423033 N-Bromo- or chloro-phthalazinones MINNESOTA MINING & MFG CO 16 Jan 1973 [17 Jan 1972] 2319/73 Heading C2C [Also in Division G2] N-Bromophthalazinone is prepared by adding dropwise bromine to a cold solution of 1-(2H)- phthalazinone in aqueous methyl alcohol followed by dropwise addition of aqueous sodium hydroxide. N-Chlorophthalazinone is prepared by mixing 1-(2H)-phthalazinone into cold aqueous sodium hypochlorite solution.
